If this is performant enough, I don't at the moment see any reason to
have it in C.  Of course, the few places that call Flookup_key from C
will need to be analyzed whether they need to call the internal
function or the Lisp wrapper, and modified accordingly.

This is not the only transformation we should apply, IMO: we should
also convert "Foo Bar Baz" into "foo-bar-baz".  See the Dired menus
for examples.
